Onshore, McDermott has designed and managed some of the world's largest pipeline projects. With more than a half-century of pipeline experience to our credit, we've earned respect for our ability to deliver successful pipeline projects even in the most challenging locations.
We've designed pipelines for transporting crude oil, natural gas, refined petroleum products, LPG, LNG, NGL, condensates, water, slurries and various chemicals—both in single-phase and multiphase flow. These pipelines have ranged in diameter from 3 inches (75 millimeters) to 5 feet (1,500 millimeters). Over the last 10 years we have executed contracts for more than 20 projects, leading to the safe and timely installation of more than 10,000 km of pipelines, where our scope included engineering, procurement, construction management and support services.
Offshore, McDermott is a leading supplier of design and installation services for pipelines and in-field flowlines, risers, and umbilicals in both shallow and deep water around the globe. With our own spoolbases and fleet of pipelay vessels, we can take sole-source engineering, procurement, construction and installation responsibility, giving our customers a single point of contact.
In addition, we provide complete design-build services for associated facilities, such as compression and pumping stations, pig traps, slug catchers, valve stations, terminals and reception facilities.
McDermott’s areas of technical expertise include:
- Geohazard and seismic design
- Crossing design, including horizontal directional drilling (HDD) and microtunneling
- Risk assessment and safety analysis
- RAM and modularization studies
- Flow assurance analysis both under steady state and transient conditions (including multiphase, multi-product, non-Newtonian and high temperature/high-pressure fluids)
- Limit state design
- Materials and welding
- SCADA and telecommunications
McDermott’s involvement in the IPLOCA Pipeline Cost Reduction Research and Development Program and our extensive in-house library of benchmark cost data for various pipeline and process facilities support our value engineering process and ensure the most cost-effective pipeline design.
The planning and execution of a pipeline project requires extensive knowledge of numerous geographical, political, regulatory, social and environmental issues. With offices worldwide, we have people in every major market who can provide the specialized knowledge and skills needed to effectively complete the pipeline scope of work.
